APPARATUS FOR DRYING PAPER, 80.

SPECIFICATION forming part of Letters Patent No. 359,446, dated March 15. 1887. Application filed October 7, 1886. Serial No. 215,573. (No model.)

section in the plane x 00, Fig. 2. Fig. 2 is a plan view. Fig. 3 is a detail view showing a roller mounted on a hollow axle, which is connected to a heating-pipe. modification.

Similar letters indicate corresponding parts.

A is a base or support, which may be constructed of any material suitable for the purpose, and which may be in a horizontal position or in a vertical position, or in any position suitable for the purpose. On this base a series of axles, B, B, B B B B B B and B are mounted parallel to one another and on a spiral or approximately spiral line. The term spiral is used in this case not strictly in the geometrical. sense, but to indicate a line which recedes from its pole by irregular steps, although, if desired, said axles may be placed on a geometrical spiral without destroying the efficiency of the apparatus. I On the base or support is also mounted aninterior exit-roller, G", on an axle, B, which axle B is inclined. A supplemental interior exit roller, O on an inclined axle, B, can also be provided. A convenient way of attaching the axle B is to form said axle as on the extension of the axle B Other means of attachment may, how- Fig. 4 shows a ever, be provided, the object being to place the supplemental exit-roller 0 at some distance from the base or support A. Said inclined rollers G" and 0 are loosely mounted on their axles.

' On the axlesB to B are loosely mounted rollers C to O and, if desired, one or more of these rollers may be provided with pulleys, so that a rotary motion can be imparted to the same. Between the rollers are a series of heating-coils, D. 13 represents the web which is to be dried. As indicated by the arrows in Fig. 2, this web is introduced into the drying apparatus over the vertical roller 0, and on reaching the interior inclined roller, 0 it is carried from the center orinterior of the spiral up to the exteriorinclined roller, C whence I desirable to impart to some or to all of said.

rollers a revolving motion by belts or pulleys or by other equivalent means.

By referring to Fig. 2 it will be seen that only one side of the web is brought in contact with the rollers O to O as the same passes through the drying apparatus, and my apparatus can therefore be used with advantage for drying webs which have been colored, printed, or stained on one side without danger of injuring the designs or the colors produced on or applied to said web.

If desired, the supplemental exit-roller 0" can be dispensed with and the fabric led off directly from the interior inclined exit-roller 0". As seen in Fig. 3, the rollers, or one or more of the rollers-as, for example, the roller C--can be mounted on a hollow axle, B, communicating by-a suitable connection with a steam-pipe, D. The rollers will thus be heated, and drying of the fabric is expedited. If desired, instead of leading the material into the apparatus at the roller 0 and out at the roller mounted on parallel axles which are situated,

on a spiral line on a suitable base, with an inclined interior exit-roller and asupplemental inclined exterior exit-roller situated at a distance from the base or support, substantially as described.

2. The combination of a series of rollers mounted on parallel axles which are situated on aspiral line on a suitable base, with an inclined interior exit-roller, substantially as described.

3. The combination of a series of rollers mounted on parallel axles which are situated on a spiral line on a suitable base, with an inclined interior exit-roller and a heating-pipe, substantially as set forth.

4. The combination, with a heating-pipe, of a series of rollers mounted on parallel hollow axles communicating with said pipe and situated on a spiral line on a suitable base, and 20 an inclined interior exit-roller, substantially as set forth.

In testimony whereof I have hereunto set my hand and seal in the presence of two subscribing; witnesses.
